Extreme Cities by Ashley Dawson: Cities, Climate and Inequality

Extreme Cities: The Peril and Promise of Urban Life in the Age of Climate Change (2017) is the book in which Ashley Dawson, a professor at the City University of New York, argued that cities are at once the main cause of climate change and its first victim, and that inequality decides who survives it. Written after Hurricane Sandy, which in 2012 flooded New York's subway and low-lying neighbourhoods and left public housing blocks without power for days while financial Manhattan recovered, the book defines the extreme city as one where extreme climate risk and extreme inequality coincide, and where official responses protect capital before people.

The geography of risk: coastal cities and a map of class

Dawson starts from the geography of risk. Most of the world's great cities are coastal, New York, Miami, Shanghai, Jakarta, Lagos, Mumbai, and sea level rise, storm surges and extreme rainfall threaten hundreds of millions of people and the ports, power plants and networks on which the global economy depends. But risk is not evenly shared: in New York, public housing projects were built on the floodable land nobody wanted, and in Jakarta or Lagos informal settlements occupy the sinking shores. The extreme city is, for Dawson, a map of class.

Climate apartheid: seawalls that protect capital

His critique targets adaptation as practised. Large resilience projects, Manhattan's BIG U from the Rebuild by Design competition, seawalls and barriers, protect the highest-value districts and push water and risk toward the neighbours; insurance and reconstruction favour owners; and the rhetoric of resilience asks communities to absorb blows they did not cause. Dawson calls that logic climate apartheid and shows how the city of capital fortifies itself while turning disaster into business opportunity, from luxury development in rebuilt zones to evictions in damaged neighbourhoods.

Occupy Sandy and disaster communism: the promise

The promise of the title lies in what happened during Sandy. When the state was slow, the Occupy Sandy network, born of the 2011 movement, organised within days the distribution of food, medicine and help in abandoned neighbourhoods, and Dawson sees in that self-organisation, which he calls disaster communism, proof that cities contain the solidarity needed to face the climate if given power and resources. His proposal is a just and democratic adaptation: protect the most exposed first, plan orderly retreats from indefensible zones with guaranteed housing, and finance the transition with those who have emitted most.

Managed retreat, climate gentrification and criticism

The book converses with Mike Davis, Naomi Klein and urban political ecology, and anticipated debates that have become central: managed retreat from the coast, climate gentrification in Miami, where high-ground poor neighbourhoods such as Little Haiti grow expensive as the rich flee the sea, and the sinking of Jakarta, which led Indonesia to plan a new capital. Critics reproach it for a tone more of denunciation than technical proposal; its defence is that the technique already exists and what is missing is deciding whom it protects.

The lesson of Extreme Cities is that there is no climate adaptation without a politics of equality. A city that fortifies itself piece by piece produces refuges for some and sacrifice zones for others; one that plans for all, with safe housing, dignified retreat and power for communities, can turn the extreme city into the place where collective survival is rehearsed. Dawson leaves planning the question Sandy made visible: when the water comes, who will have light and who will not.
